Operating Procedures

Power Control Procedure

A suggested power-on procedure for the chassis is as follows:

1.Ensure that all modules and cabling are properly configured and installed. Also check that all required external cabling (to peripherals) is correctly installed.

2.Plug in the AC line cord (at the rear of the chassis) and connect the cord to an AC power source.

3.Set the power switch at the front of the chassis to (ON). The power supply cycles up and the cooling fans immediately come on.

4.Power up any peripheral equipment interfaced to the chassis that has its own power on/off switch.

A suggested power-off sequence for the chassis is as follows:

Note Ensure that proper software shutdown procedures have been executed before you continue.

1.Power down any peripheral equipment interfaced to the chassis that has its own power on/off switch.

2.Set the power switch to OFF. The power supply cycles down, and the cooling fans stop running. For the AC chassis only, the power supply fan will continue to run.
